Update Angular versions

This updates the index-async.html file to use the latest versions of
AngularJS and AngularFire.
Add School Profile page and new routing mechanism

This commit adds a new routing mechanism that does not require routes to
be manually added for each page; instead, it attempts to serve all uris
given to it and redirects to home if they are not available.  As a test
of this routing mechanism, this commit also adds the beginnings of a
school profile page.
